摘要
温度、湿度、气体颗粒浓度等参数是鉴定环境质量必不可少的参数。采用DHT11温湿度传感器检测环境温湿度及CP-15-A4传感器检测大气颗粒浓度,LCD显示检测的数值。以超低功耗的MSP430单片机为主控芯片,充分运用微机丰富的逻辑判断和数值运算以及中高档MSP430单片机相关寄存器功能,基于传感器特点,针对现有的单片机应用理论,介绍了具体设计时各种问题的解决方法,并通过实验证明了所提方法的正确性。
The parameters such as temperature,humidity and gas particle concentration are essential for the identification of environmental quality.This design used DHT11 temperature and humidity sensor to detect ambient temperature and humidity,CP-15-A4 sensor to detect atmospheric particle concentration,and liquid crystal display(LCD)to display the value of detection.This design used ultra low power MSP430 chip microcontroller to make full use of the abundant logic judgment and numerical calculation and high-grade MSP430 chip register function.Based on the characteristics of the sensor,aiming at the application of microcontroller existing theory,this paper introduces the methods of solving a variety of problems in the concrete design and the experiments verify the correctness of the proposed method.
